Description

The invention relates to an adapter for connecting the beam path of an optical recording device, in particular a camera, with the beam path of an optical observation device according to the preamble of claim 1.

Such adapters are known. Since even the smallest movements between the camera and optical observation device, such as a telescope, significantly reduce the image quality, takes place in the known adapters a mechanically fixed connection between the camera and observation device.

That's how it is US-A-5,053,794 an adapter known which is screwed onto the internal thread of a camera lens provided on the filter element, while three are provided for attachment to the eyepiece of the observation device by 120 ° offset radially extending screws.

Furthermore, an adapter in the market, which is intended for a provided with a unscrewed eyecup monocular. The commercially available adapter is screwed on the one hand to the thread, which is provided on the camera lens for filters, sun visors and the like, and on the other hand to the thread on the eyepiece after unscrewing the eyecup.

The screwing and unscrewing of the adapter is cumbersome and time consuming. Also, the known adapters are only suitable for cameras or observation devices that have corresponding threads.

The object of the invention is therefore to provide an adapter which is easily and quickly attachable to any camera lenses.

This object is achieved by an adapter for connecting the beam path of an optical recording device, in particular a camera, with the beam path of an observation device with a fixing portion for attachment to one of the two devices, wherein the adapter for centering the optical axis of an objective of the recording device on the optical axis of an eyepiece of the observation device has two centering devices, wherein a first centering the eyepiece of the observation device and a second centering device is associated with the lens of the recording device and wherein one of the two centering device through the mounting portion for centering and holding the eyepiece or on a Housing part of the observation device or on the lens or on a housing part of the recording device is formed and the second centering for need centered aligned attachment or recording on the lens or on a housing part of the recording device or on the eyepiece or on a housing part of the observation device is formed.

Thus, the adapter preferably on the one hand on a mounting portion, with which it can be fastened to the observation device, and on the other for centering the optical axis of the lens of the camera on the optical axis of the eyepiece of the observation device a plug-in, in which the camera lens is pluggable.

That is, the camera lens is slidably mounted in the adapter, so not fixed in the longitudinal direction. It has been found that the image quality depends essentially only on the fact that the optical axes of the camera lens and the eyepiece of the observation device are aligned with each other, thus centering the optical axis of the lens of the camera on the optical axis of the eyepiece. A shift in the direction of the common optical axis, however, has little influence on the image quality. That is, the fine motor skills of a person who holds the camera with one hand and possibly the observation device with the other hand, is completely sufficient to get flawless images. The camera lens can be pushed into the adapter as far as the stop on the eyepiece of the observation device. However, it may also be provided a separate stop in the adapter.

The insertion portion of the adapter according to the invention preferably has a variable inner diameter in order to center camera lenses with different diameters.

The adapter according to the invention is intended in particular for observation devices whose eyepiece is provided with an eyecup. The eyecup is made of soft rubber or another rubber-elastic material and prevents interference by lateral stray light and allows comfortable support of the device on the forehead.

In order to be able to be attached quickly to the eyepiece, the attachment portion of the adapter according to the invention is preferably designed attachable to the eyepiece, in the radial direction to the optical axis of the eyepiece. For this purpose, the adapter may have two spring tongues which resiliently engage on one side or the other of the eyepiece. This aligns the adapter with the optical axis of the eyepiece. The fixation in the longitudinal direction can be accomplished by the eyecup. That is, the spring tongues are preferably designed so that they engage behind the eyecup resiliently when plugged into the eyepiece adapter. However, the attachment portion may also be designed differently. Thus, the adapter may be e.g. have a funnel-shaped attachment portion which is placed on the eyecup.

The eyecup can be attached to the eyepiece with an eyecup holder. The eyecup holder is preferably designed such that the distance between eyecup and eyepiece can be changed, for example by displacement or a helical screw. This is particularly important for spectacle wearers, as the field of view increases the closer the eye is to the eyepiece.

The eyecup holder can be used according to the invention for receiving the adapter. Thus, the adapter may be formed by an elastic ring which abuts with its outer wall on the adapter holder, so that the outer wall forms the mounting portion, wherein the camera lens is inserted into the elastic, held by the eyecup holder clamped ring, so the inner wall of the elastic ring forms the male portion of the adapter.

Due to its elasticity, the elastic ring can be adapted to camera lenses with different diameters. He can do this, for example, as a hose ring or made of a rubber-elastic material.

In order to use the adapter according to the invention for cameras whose lens diameter is very different, the adapter can also by a set of elastic rings with different inner diameter are formed.

The actuating ring may have on its inside circumferentially wedge-shaped from the inside outwardly extending, separated by stages control surfaces, each attacking one of the jaws. For this purpose, the jaws against the control surfaces, for example, be spring loaded. By turning the actuating ring, which preferably surrounds the jaws, the jaws can be moved synchronously radially inwards.

Instead, the jaws can also be designed as leaf springs. In this case, each leaf spring may be fixed in the circumferential direction with one end to the actuating ring, while the other end of the respective leaf spring stationary, that is rotatably connected to the mounting portion of the adapter. By turning the actuating ring, the leaf springs can thus be bulged radially inward to match the diameter of the camera lens.

In order to secure the rotational position of the actuating ring, a grid can be provided between the actuating ring and the part of the adapter connected in a rotationally fixed manner to the fastening section. Furthermore, a scale or the like marking can be provided on the actuating ring and / or the part of the adapter which is connected in a rotationally fixed manner to the setting section in order to set the previously determined rotational angle of the actuating ring for a specific camera lens diameter.

According to a further embodiment of the invention, the jaws can be displaced radially be guided. For displacement of the jaws, the actuating ring may have in the circumferential direction obliquely from inside to outside extending control grooves, engages in each of which a jaw, for example with a projection.

To guide the jaws radial recesses may be provided in an intermediate ring, which is arranged between the mounting portion and the actuating ring.

In an advantageous embodiment of the adapter is provided that for the radial adjustment of the jaws, a motor is arranged in the adapter. In addition, even between the engine and the jaw operating gear, a slip clutch be interposed, so as to limit the force acting on the lens enclosed between the jaws force.

The spring tongues 11 are provided with openings 28 to which a loop can be attached, with which the adapter 1 can be suspended when not in use, for example, on the strap of the observation device.

In the embodiment according to FIG. 10 the adapter 1 is formed by an elastic ring 30. The eyecup 8 is attached to the eyepiece 3 with an eyecup holder 31. The elastic ring 30 is arranged in the eyecup holder 31 in front of the eyepiece lens 32. The elastic ring 30, which may be formed as a tube, lies with its outer wall 33, which forms the attachment portion of the adapter 1, with a clamping fit inside the eyecup holder 31, while the inner wall 34 of the ring 30 forms the insertion portion of the adapter 1.

The elastic ring 30 may instead of a tube also made of a foam or solid material, such as rubber or a rubber-elastic material.

In the embodiment according to FIG. 11 the attachment portion 4 is formed in the same manner as the attachment portion 4 of the embodiment according to Figure 1-9 so in terms of the fastening portion 4 of the embodiment according to FIG. 11 to the above description of the embodiment according to Figure 1-9 can be referenced.

The attachment portion 4 is provided in this embodiment with a sleeve 35 in which an elastic ring 36 is arranged. The elastic ring 36 may be formed in the same way as the elastic ring 30 after FIG. 10 Thus, with respect to the ring 36 to the description of the embodiment according to FIG. 10 can be referenced.

In the elastic ring 36, the camera lens 2 is inserted, so it forms the male portion in this embodiment. The ring 36 may be designed to be displaceable in the longitudinal direction. These are in accordance with FIG. 11 Longitudinal slots 37 are provided in the sleeve 35, through which an actuator 38 connected to the ring 36 protrudes outward to move the ring 36 can. As in FIG. 11 can be seen, the attachment portion 4 and the sleeve 35 may be integrally formed.

According to the two embodiments Fig. 12 or 13 and 14, the adapter 1 is formed by a sleeve 40. The sleeve 40 has on its inside a funnel-shaped widening portion 41, which is plugged onto the eyecup 8 and the attachment portion 4 is formed.

The jaws 12 are formed in these two embodiments by rocker 42, which are hinged at its front, so the camera lens 2 facing the end transverse to the longitudinal axis of the adapter axis 39 pivotally mounted on the sleeve 40. The rocker arms 42 are bent outwardly toward the eyepiece 3, so that they come to rest flatly with their end sections 43 on the camera lens 2.

In the embodiment according to Fig. 12 The three rocker arms 42 are spanned by a spring ring 44, which loads it to bear against the camera lens radially inwardly.

In contrast, in the embodiment according to FIGS. 13 and 14 the radial position of the rocker arm 42 adjustable. For this purpose, an actuating ring 46 is rotatably mounted in the sleeve 40, which surrounds the three rocker arm 42 at a distance from its pivot axis 39. The actuating ring 46 has on its inside in the circumferential direction wedge-shaped from the inside to the outside extending, separated by steps 45 control surfaces 47 which abut respectively on one of the rocker 42.

The actuating ring 46 is connected to an actuating element, not shown, which projects through a not shown in the circumferential direction extending slot in the sleeve 40 to the outside. Further, a ratchet or the like locking device between the sleeve 40 and the actuating ring 46 may be provided to fix the rotational position of the actuating ring 46.

In the embodiment according to FIGS. 15 and 16 the attachment portion 4 is formed in the same manner as the attachment portion according to Fig. 12 Thus, with respect to the attachment portion of this embodiment to the above description of the attachment portion according to Fig. 12 can be referenced.

In the embodiment according to Fig. 15 the jaws 12 are formed as leaf springs 50. Further, an actuating ring 51 is rotatably mounted on the sleeve 40. Each leaf spring 50 is fixed in the circumferential direction with its one end 52 on the actuating ring 51 and with its other end 53 on the sleeve 40.

By rotating the actuating ring 51, the leaf springs 50 can be arched inwardly to abut the camera lens to center it. On the side facing the camera lens, the leaf springs 50 have concave indentations 54 for surface contact with the camera lens.

Also in this embodiment, a latching device is provided, which is formed by a locking ring 55 arranged in the actuating element 55, which is spring-loaded on the sleeve 40 and engages in the sleeve 40 in provided recesses.

The Fig. 17 shows one to the in the Fig. 1 to 9 shown adapter alternative embodiment of the adapter 1. The insertion portion 5 of the adapter 1 has two jaws 12 offset by 180 °. The jaws 12 are each formed with two obliquely arranged and mutually facing cheek flanks 56, so that the camera lens 2 can be centered between the jaws 12. The cheek flanks 56 are also preferably planar and symmetrically shaped to each other. The adjustment of the jaws 12 takes place as already in the embodiment of the Fig. 1 to 9 described by turning the actuating ring 18th

In a further alternative embodiment of the adapter 1 can be provided that the radial adjustment of the jaws 12 by means of a motor 57 (dashed lines drawn) takes place. For the preferably electric motor 57 a battery as a power source and a controller 58 are provided in the adapter 1. According to this embodiment of the adapter 1, the actuating ring 18 serves as a switch, which causes the jaws 12 to open when rotated in one direction and, when rotated in another direction, to cause the jaws 12 to move toward the camera lens 2 inserted between them. The motor 57 is preferably coupled by the interposition of a slip clutch to the jaws 12 actuated gear, whereby a force limit of the force exerted by the jaws 12 on the camera lens 2 force is achieved and thus damage to the lens 2 can be avoided. A limitation of the forces acting on the objective 2 can alternatively also be effected with the aid of correspondingly arranged force sensors (not shown).

Fig. 18 shows another to the representation according to the Fig. 1 to 9 Alternative embodiment of the adapter 1. The jaws 12 are each arranged pivotable with respect to an axis parallel to the longitudinal axis 17 of the adapter 1 aligned. The cheek flank 56 of the jaws 12 preferably has a convex curvature. The adjustment of these jaws 12, as described above, done manually or driven by a motor.

The Fig. 19 shows an embodiment of the adapter 1 with a plug-in portion 5 which is formed in the manner of an iris diaphragm. For this purpose, the adapter 1 has jaws 12, which are shaped like lamellas and in each case are pivotable relative to an axis parallel to the longitudinal axis 17.

The Fig. 20 shows an embodiment of the adapter 1 with a pneumatically actuated plug-in section 5. The case provided tubular elastic ring 30 is connected to a pump 59 so that it can be more or less inflated. Thus, the inner diameter of the elastic ring 30 is dependent on that by the pump 59 generated pressure changeable. Increasing or reducing the pressure is triggered by actuating a switch 60 or 61, wherein the control 58, a corresponding control of the pump 59 is carried out. In order to monitor the pressure in the elastic ring 30, a pressure sensor 62, which is in signal communication with the control 58, may be provided in this or in the pump 59. The pump 59 is thus preferably a motor-driven pump. Alternatively, however, it is also possible to provide a manually actuatable pump 59, for example a bellows.

As has already been stated in the introduction, the adapter 1 is suitable for various types of optical recording devices or cameras, for example a digital camera, a camera with a film, a video camera or a film camera. The adapter 1 thus serves to connect the beam path of an optical recording device with the radiation path of an observation device. According to the embodiments of the adapter 1 described above, it is provided that the attachment portion 4 is attached to the observation device or to the eyepiece 3 of the observation device. On the other hand, the lens 2 of the camera is inserted into the insertion portion 5 of the adapter 1. The attachment portion 4 and the insertion portion 5 each serve as a first and a second centering device with which the eyepiece 3 of the observation device and the lens 2 of the recording device with respect to the longitudinal axis 17 of the adapter 1 are centered. Thus, the optical axis 6 of the objective 2 of the recording device is centered on the optical axis 7 of the eyepiece 3 of the observation device. The adapter 1 may alternatively be designed such that the attachment portion 4 can be fastened for attachment to the objective 2 of the recording device and on the other hand the eyepiece of the observation device is inserted into the insertion portion 5. However, the mutual connection of the beam paths of the optical recording device and the observation device can be done not only by attaching or applying the adapter 1 to a housing part of the eyepiece 3 or on a housing part of the lens 2. Alternatively, it is also possible to achieve the centering of the optical axes 6, 7 by attaching or applying the adapter 1 to another housing part of the observation device or to a housing part of the recording device. The relevant housing part of the observation device should therefore be in fixed spatial relationship with the optical axis 7 of the eyepiece 3. This applies analogously to the relevant housing part of the recording device and the optical axis 6 of the objective 2.

The Fig. 21 shows a two-component adapter 1. This is formed by a first adapter part 71 with the mounting portion 4 for attachment to the eyepiece 3 and by a second adapter part 72 with a mounting portion 73 for attachment to the camera lens 2. The mounting portion 4 of the first adapter part 71 forms A first centering device 74 for centering with respect to the common longitudinal axis 17 of the adapter 1. Likewise, the mounting portion 73 of the second adapter part 72 forms a second centering device 75. On its side facing away from the first centering device 74, the first adapter part 71 has a further centering device 76. Likewise, on the second adapter part on the side facing away from the second centering device 75, a further centering device 77 is provided. These further centering devices 76, 77 are designed so that the first and the second adapter part 71, 72 can be brought centered aligned with each other. That is to say the further centering device 76 of the first adapter part 71 can be brought into contact with the second centering device 77 of the second adapter part 72. The further centering devices 76, 77 of the first and the second adapter part 71, 72 are preferably formed with mutually complementary contact surfaces 78, 79. As shown in FIG Fig. 21 are the contact surfaces 78, 79 formed by the longitudinal axis 17 of the adapter 1 symmetrical conical surfaces with the same cone angle. When assembling the two adapter parts 71, 72, the further centering device 77 of the second adapter part 72 is received in the further centering device 76 of the first adapter part 71 and brought into abutment, wherein at the same time alignment of the longitudinal axes takes place on the common longitudinal axis 17. In contrast to the attachment of the adapter parts 71, 72 on the lens 2 and the eyepiece 3 is provided between the other centering devices 76, 77 only a system or a relatively easily detachable attachment. This system can additionally be supported by the fact that magnets for generating attractive forces between the first and the second adapter part 71, 72 are arranged in the area of the contact surfaces 78, 79. The attractive forces of the magnets are limited in such a way that a relatively smooth redetachment of the two adapter parts 71, 72 from each other is possible.
